When dealing with nausea from motion sickness or illness, the best approach is to consume bland, low-odor foods that are easy for the stomach to process. The gold standard is the BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast. These foods are starchy and low in fiber, helping to bind the stomach without causing irritation. Ginger is perhaps the most scientifically backed natural remedy; ginger lozenges, ginger ale (made with real ginger), or fresh ginger tea can help accelerate gastric emptying and settle the digestive system. Dry, salty snacks like saltine crackers or pretzels are also excellent for absorbing excess stomach acid and replacing lost electrolytes. Cold, clear liquids like apple juice or electrolyte drinks are better tolerated than hot beverages, as they emit fewer odors that might trigger a gag reflex. It is generally advised to avoid fatty, greasy, spicy, or extremely sweet foods, as these require more effort to digest and can worsen a queasy feeling.
